Calyx’s Ratings Platform currently identifies “CORSIA eligible” units.  We thought it would be helpful to describe in more detail what this means and why it can be challenging.

The Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) is a global scheme set up by the International Civil Aviation Organisation (ICAO) to regulate the carbon offset market for international aviation since emissions from international flights are outside the scope of the Paris Agreement. As such, ICAO determines which emissions reductions can or can not be used to offset emissions from international flights for those countries that opt into the scheme.
